[oom'nNED SOCKET AND swrron FOR ELECTRIC LIGH'rs- To all whom it may concern:

Be it known that I, DGUGLAS A. BATLEY, a

I citizen of the United States, residing at Fort iss Worth, in the county of Tarran t and State of Texas, have invented. certain newand useful. Improvements. in Combined Sockets and Switches for Electric Lights, of which the following is a specification.

My invent-ion relates to sockets for electric light globesand more particularly to sockets whlch are provided with a switch,

and the object is to provide a socket with a switch so that the number of lighted globes in achandelier can be varied. or so that a partof the globes can be lighted while others are not lighted, and the advantage of this invention is that the lighting of the globes of a chandelier can becontr'olled from a single socket, as the lowest socket in the chandelier and the particular light or lights desired can be utilized. j

Other objects and advantages will befully explained in the following descriptionand the invention will be more particularly pointed out in the claims- Reference is had to the accompanying drawings which form a part of this application.

Figure 1 is a perspective view of a chahdelier provided with five globes. Fig. 2 is a side elevation of the interior -mechanism, the globe holding portion being shown in section- Fig. 3 is a similar view with the globe holder omitted and showing the part of the socket shown in the left of Fig. 2, that is, the socket is turned one quarter. Fig. 1 is an inverted view of the socket. Fig. 5 is a detail view of the keys and hammers. Fig. ti is a diagrammatic view of the circuits for the different globes.

Similar characters of reference are used to indicate the same parts throughout the several views.

The general construction of the socket used is the same as the sockets in use. The socket is provided with insulating plates A a d B which are connected by brackets 1, and 12 which space the blocks or olates A and B apart and hold the same at xed distance. The wire 10 is the usual feed wire to the socket contact, which makes connection through the bracket 1, screw 2, and bolt 13 to socket 1 1. A wire 9 is the additional feed wire for the switch contact.

16 indicates the usual socket key and 15 indicates the switch key? A' metal strip is Specification of Letters Patent.

attached to plate B by a screw 26 and a contact 8 is formed 'on the upper end and a socket contact 25 is formed on the lc-wenend.

The socket key 16 operates contact- 8 by means of the cam 6 which is rigid withv the key bolt 17 which is journalcd in bracket or support 18 which is electrically attached to the bracket or contact post 4, or to the basev of sai d bracket. .he switch cont-act earn 5 is-rigid with a sleeve 20 which is mounted on bolt 17 and journaled in the bracket 19 which is also electrically attached to the.

base of the bracket 1. An annulus 15 is rigid with the sleeve 20 and constitutes the switch key. The key 15 operates the contact 7 which is electrically attached to the bracket 12. The switch contact cam 5 is held either.

in or out of contact with contact'7 by means of a'. washer 21 and a spring, The socket" cam 6 is held ther in or out of contact with the. contact-S by means of a washer 23 and spring 24. The wire 9 is electrically at-- tached to the bracket: 12 and consequently to the contact 7, and, constitutes the switchwire. The wire 11 is electrically connected to the bracket 4 and consequently to the key supports 18 and 19. The keys 15 and 16 operate independently of each other and there is no electrical connection between the sleeve 20 and the bolt or shaft 17. The wire 9 is the switch feed wire and the wire 11 serves to close a .circuit with either wire 9'01- wire 10. Either key 15 or key 16 can be used to close a'circuit through-wire 11, but key 15 can close a circuit only through Wires 9 and 11, and key 16 can close a circuit only through wires .10 and 11.

27 is used to indicate the socket-illustrated in detail in the drawings. The socket 27 is the central socket of a chandelier which is provided with -a number of sockets for globes 28. The wires 9,10, and 11 can be grouped to be inclosed in the pipe extending from the socket, and then extended up a chain 29 to a pan 30 from which the globes '28 are suspended. The wires 10 and 11 maybe considered the usual wires which extend to and from the source of electricity. The wire 10 extends directly to the socket 27 as shown in detail,.,but the wire 11 extends from thesocket 27 first to a junction 31 within the pan 30 andfrom the junction 31 out with the wire 10. "One arm .32 of each circuit for the globes 28 connects with a junction 33 to which the wire9 is electrically connected. and the other arm 34 of each circuit for the globes 28 is connected to the junction 31 to which the wire 11 is electrically connected. Thus the circuits for the globes 28 can be closed only by the key 15 for lighting ,these globes and .the circuit for the central globe 35 can be closed only by the key 16.

WVit-h the construction and arrangement shown, the central light of the chandelier can be used alone, or the lights 28 can be used without the central light, or the central light and the other lights can all be used together. This illustration shows only one application of the use of the invention. It

is apparentthat adiflerent division of the,

lights can be made without departing from my invention. One or more of the lights 28 could be used with the central light 35 if desired by re-arranging the wiring. The object is to employ one circuit from the main switch to the chandelier and then to employ as many subsidiary circuits as may be desirable which can be controlled from one of the sockets in the chandelier. Other changes can be made without departing from my invention. Instead of the keys l5 and 16,2.

chain or a lever can be used to operate the circuits for lighting purposes.

lVhat I claim, is, 1. A combined socket and switch for elec- Copies of this patent nay be obtained for he cents each, by :ddressl Washington, D. C."

'pleting the circuit through said socket from said feed wire to said return wire, a switch wire, a contact electrically connected to said switch wire, a cam and a key operating independently of said first named cam and key for completing a circuit from said feed wire to said switch wire, and sockets operatively connected with said switch wire and with said return wire.

2. A combined socket and switch for electric light chandeliers comprising a socket and a feed wire connected thereto, a return wire for said socket, a contact connected to said return wire, a key provided with a shaft and a cam rigid therewith for closing a circuit from said feed wire to said return wire, a switch wire, a plurality of sockets electrically connected with said switch wire and with said return wire, a contact connected with said switch wire, and a key having a sleeve and a cam rigid therewith mounted on-. said shaft and operating independently of said first named key and its contact for closing a circuit from said feed wire through said socket to said switch'wire for lighting said plurality of sockets.

In testimony whereof, I set my hand in the presence of two witnesses, this 2nd day of F ebruury, 1912.
